Hi
I was about tell that i have written an MPI code in which i have specified
only for the communication between nodes and i dont whether can i run
program as per my requirement i.e to use the cores present in my node (all
4 cores). So my doubt is should i need to include pthreads or the program

I'm afraid I can't parse that sentence; I don't know what you mean.

Hi Tom,
Thank you.
I haven't still changed my code to run when threading is needed (presently
working).
I have doubt that when i calculate the MPI ranks using the MPI command it
gives only the nodes which have given in a host file.
But how can i calculate the MPI ranks as you have told i.e N=H(
Hi Seshendra,
If you have implemented hyperthreading by Enabling it in the BIOS, then when
you look at
cat /proc/cpuinfo output, you will see 2x the # of CPUs than the number of
cores on your system.
If that number of CPUs showing on a node = H, and the number of nodes in your
cluster with thi
